Bidirectional Interference Between Simulated Driving And Speaking, Christopher Dromey, Kelsey Simmons

Faculty Publications

Purpose: This study relied on acoustic measures of connected speech and several indices of driving performance to quantify interference between speaking and simulated driving. Method: Three groups of 20 younger (ages 20–30 years), middle-age (ages 40–50 years), and older (ages 60–71 years) adults produced monologues and completed a simulated driving task, which involved maintaining a constant speed and lane position on a freeway. Both tasks were completed separately and concurrently. Results: There were significant divided attention effects, with a reduced speaking time ratio, and increases in vocal intensity, speed variability, and steering wheel adjustments. There was a significant between-subjects age …

Faculty Publications

This study evaluated listeners’ ability to identify the gender of preadolescent children from speech samples of varying length and linguistic context. The listeners were presented with a total of 190 speech samples in four different categories of linguistic context: segments, words, sentences, and discourse. The listeners were instructed to evaluate each speech sample and decide whether the speaker was a male or female and rate their level of confidence in their decision. Results showed listeners identified the gender of the speakers with a high degree of accuracy, ranging from 86% to 95%. Significant differences in listener judgments were found across …

An Intensive Book Camp Approach To The Remediation Of Speech Sound Disorders: A Case Report, Shawn L. Nissen, Melanie E. Peris, Kristine Tanner

Faculty Publications

Background: Understanding treatment dose is essential to optimizing therapeutic frequency and intensity for speech sound disorders. Intensive therapies, known as boot camp approaches, have proven efficacious in certain speech therapy contexts such as voice disorder treatment. However, few data exist regarding intervention intensity for developmental speech sound disorders. Method: This investigation examined the effects of an intensive boot camp speech therapy approach to remediate interdental /s/ production over two consecutive days. Treatment occurred in morning and afternoon blocks for a total of 5.5 h per day. Auditory-perceptual ratings were used to evaluate /s/ productions pre-treatment, immediately post-treatment, and one week …

Using Real-Time Visual Biofeedback For Second Language Instruction, Shawn L. Nissen, Rebecca Nissen

Faculty Publications

This demonstration will illustrate how using real-time visual biofeedback, through a relatively new type of electropalatographic (EPG) sensor, might facilitate improved pronunciation for learners of a second language (L2). The manner in which the EPG sensor is created and its use to track lingua-palatal articulation patterns will be described to individuals. This presentation will also include an explanation of how a student can visualize the contact patterns of their speech using the associated instructional software. A brief tutorial on the features of the instructional software will also be explained during the “show and tell” presentation.

Is It The Sex, The Romance, Or The Living Together? The Differential Impact Of Past Sexual, Romantic, And Cohabitation Histories On Current Relationship Functioning, Dean M. Busby, Brian J. Willoughby, Melissa L. Mcdonald

Faculty Publications

Before their current relationship, individuals may have had a variety of previous relationships such as romantic relationships, sexual relationships, and cohabiting relationships. In this study, we explored the common or shared influence of these 3 types of previous relationships, and the unique influence of each type, on current relationship functioning. With a sample oof more than 4,000 individuals we found that there was a significantly negative shared influence for previous romantic, sexual, and cohabitation relationships on current relationship attitudes, sexual satisfaction, commitment, and stability. The effects were largely similar for women and for men. It appears that on average the …

Associations Of Ambivalent Leadership With Distress And Cortisol Secretion, Wendy C. Birmingham, Raphael M. Herr, Frenk Van Harreveld, Bert N. Uchino, Adrian Loerbroks, Joachim E. Fischer, Jos A. Bosch

Faculty Publications

Ambivalent social ties, i.e., whereby a relationship is evaluated simultaneously in positive and negative terms, are a potential source of distress and can perturb health-relevant biological functions. Social interactions at the workplace, in particular with supervisors, are often described in ambivalent terms, but the psychological and psychobiological impact of such interactions has received little scientific attention. The current study examined associations between ambivalent attitudes towards one’s supervisor, perceived distress (general and work-related), and diurnal dynamics of the stress hormone cortisol. 613 employees evaluated their supervisor in terms of positive and negative behaviors, which was combined into an ambivalent index. Higher …

Rank And File Equity Compensation And Earnings Management: Evidence From Stock Options, D. Kip Holderness Jr., Adrienna Huffman, Melissa F. Lewis-Western

Faculty Publications

The wide-spread use of rank and file equity-based compensation suggests that executives believe that rank and file employees can affect firm outcomes, and some research supports this view. If equity-based incentives influence rank and file employees’ productive efforts, they might also influence their earnings management decisions. We find that increases in rank and file employees’ option-based compensation—our proxy for equity-based compensation—are associated with increases in earnings management and that this relation is attributable to real activities (as opposed to accrual) earnings management. Cross-sectional tests indicate that the relation is stronger when rank and file option compensation is likely to generate …

Framework Of Affordances For Virtual Reality And Augmented Reality, Jacob H. Steffen, James E. Gaskin, Thomas O. Meservy, Jeffrey L. Jenkins, Iopa Wolman

Faculty Publications

Virtual reality (VR) and augmented reality (AR) technologies continue to grow and present possibilities to change the ways we learn, accomplish tasks, and interact with the world. However, widespread adoption has continually languished below purported potential. We suggest that a more complete understanding of the underlying motives driving users to take advantage of VR and AR would aid researchers by consolidating fragmented knowledge across domains and by identifying paths for additional inquiry. Additionally, practitioners could identify areas of unmet motives for using VR and AR. To examine the motives for virtualization, we draw upon Gibson’s seminal work on affordances to …

The Relationship Between Perceived Stress And Problematic Social Networking Site Use Among Chinese College Students, Xiang-Ling Hou, Hai-Zhen Wang, Tian-Qiang Hu, Douglas A. Gentile, James Gaskin, Jin-Liang Wang

Faculty Publications

Background and aims: Perceived stress has been regarded as a risk factor for problematic social networking site (SNS) use, yet little is known about the underlying processes whereby confounding variables may mediate or moderate this relationship. To answer this question, this study examined whether depression and anxiety mediated the relationship between perceived stress and problematic SNS use, and whether these mediating processes were moderated by psychological resilience and social support. Methods: Participants were 641 Chinese college students who completed anonymous questionnaires measuring perceived stress, depression/anxiety, psychological resilience, social support, and problematic SNS use. Results: The results showed that (a) depression/anxiety …

Recreation Trends, Service Utilization, And Future Directions For Morale, Welfare, And Recreation Programs, Camilla Hodge, Karen Melton, Mat D. Duerden

Faculty Publications

In 2017, nearly 97% of Americans had time for leisure or recreation each day, and on average, that daily time for recreation (i.e., the time outside of work and household activities) exceeded five hours (“Average hours per day spent in selected leisure and sports activities by age,” n.d.). Where and how Americans use time for recreation has far-reaching implications for their physical and mental health (Payne, Ainsworth, & Godbey, 2010). Physical and mental health are key components related to the readiness and retention of military service members; therefore, Morale, Welfare and Recreation (MWR) services are positioned to support the readiness …

Effects Of Seawater On Carotenoid Production And Lipid Content Of Engineered Saccharomyces Cerevisiae, Yuqi Guo, Shangxian Xie, Joshua Yuan, Katy Kao

Faculty Publications

The use of seawater in fermentation can potentially reduce the freshwater burden in the bio-based production of chemicals and fuels. We previously developed a Saccharomyces cerevisiae carotenoids hyperproducer SM14 capable of accumulating 18 mg g−1 DCW (DCW: dry cell weight) of β-carotene in rich media (YPD). In this work, the impacts of seawater on the carotenoid production of SM14 were investigated. When using nutrient-reduced media (0.1× YNB) in freshwater the β-carotene production of SM14 was 6.51 ± 0.37 mg g−1 DCW; however in synthetic seawater, the production was increased to 8.67 ± 0.62 mg g−1 DCW. We found that this …

Communities And Libraries In Times Of Crisis: A Journey Of Knowledge Inquiries In South Carolina, Feili Tu-Keefner

Faculty Publications

In October 2015, several counties in South Carolina experienced catastrophic flooding that caused severe damage. Using a framework for risk communication preparedness and implementation recommended by public health experts, this study investigated public libraries and their legitimacy as partners of public health agencies during and after a disaster. The results show that the libraries in the areas affected created disaster-recovery centers, illustrating their value in facilitating emergency response and recovery. However, the findings also show librarians were not fully prepared to provide disaster and health information, especially through online venues. Information and technology literacy issues created barriers for community members …

The Lived Experience Of Work And Career Among Individuals With Bipolar Disorder: A Phenomenological Study Of Discussion Forum Narratives, Susan R. Rathbun-Grubb

Faculty Publications

Individuals with invisible chronic illnesses are often at a disadvantage in the workplace in terms of job security, promotion, and occupational success. Because little is known about the use of public online support forums to help patients with mental health disorders cope with the impact their illness has on their work and career, this research identifies and examines online forum posts related to employment by contributors with bipolar disorder. Seven percent of the total eligible posts from four discussion forums (n = 7,712) contained mentions of work and career (n = 572). A thematic analysis of the 572 posts is …

The Role Of Pressure Groups And Problem Definition In Crafting Legislative Solutions To The Opioid Crisis, Taleed El-Sabawi

Faculty Publications

Organized interest groups and federal administrative agencies have historically been influential in defining problem drug use during nationwide crisis. As such, the manner in which these pressure groups defined the problem may have influenced or, at least, provided support for legislators’ decisions to shy away from a criminal justice approach and towards acceptance of a more “health-oriented” — one that did not comprehensively address demand factors or demonstrate a commitment to reforming U.S. drug policy to meet international standards of best practice. In an effort to provide a snapshot of what such involvement may look like, this article explores the …

Half-Baked: The Science And Politics Of Legal Pot, Joelle A. Moreno

Faculty Publications

Weed, herb, grass, bud, ganja, Mary Jane, hash oil, sinsemilla, budder, and shatter. Marijuana – whether viewed as a medicine or intoxicant – is fast becoming a part of everyday life, with the CDC reporting 7,000 new users every day and the American market projected to grow to $20 billion by 2020. Based on early campaign rhetoric, by that same year the U.S. could have a pro-marijuana president.

Despite its growing acceptance and popularity, marijuana remains illegal under federal law. Like heroin, LSD, and ecstasy, marijuana is a DEA Schedule I drug reflecting a Congressional determination that marijuana is both …

Using Science To Build Better Learners: One School's Successful Efforts To Raise Its Bar Passage Rates In An Era Of Decline, Louis N. Schulze Jr.

Faculty Publications

What measures can law schools take to improve student performance and bar passage? The answer is not what you think.

Recent developments in the science of learning show that most law students learn wrong. In fact, ineffective methods of learning pervade all levels of education. We now know that widely accepted learning and study strategies that were once considered gospel are actually deeply flawed. Yet we still embrace and propagate those myths.

Meanwhile, bar passage rates and law student performance are plummeting. Everyone in legal education is asking “what can we do?” But, “what can we do?” is the wrong …

Carrots, Sticks And Problem Drug Use: The Law Enforcement Lobby's Contribution To The Policy Discourse On Drug Use & The Opioid Crisis, Taleed El-Sabawi

Faculty Publications

Despite the growing support for the idea that problem drug use should be treated like a chronic medical disease, some law enforcement interest groups, including trial court judges associations, prosecuting attorneys associations, and police associations (“law enforcement groups” or “criminal justice actors”), continue to argue for the use of the criminal justice system to address the nation’s drug crises. The justification for the use of the criminal justice system to oversee the psychological and medical treatment of persons with substance use disorders (SUDs) is based on the belief that persons with SUDs are deviants, who cannot refrain from engaging in …

The Contribution Of Family Leisure To Family Functioning And Family Satisfaction Among Urban Russian Families, Mikale Williamson, Ramon Zabriskie, Jasmine Townsend, Peter Ward, Gilbert Fellingham, Irina Kuznetsova

Faculty Publications

The purpose of this study was to examine how both family leisure involvement and family leisure satisfaction contributed to the explanation of variance in family functioning and satisfaction with family life among urban Russian families (n = 597). As an initial examination of family leisure functioning in the Russian culture, mixed model analysis accounted for family-level and individual level variance, and indicated core family leisure satisfaction was the strongest predictor of all aspects of family functioning and satisfaction with family life, a pattern similar across other cultures. There were also positive relationships between balance family leisure and various aspects of …

Moral Development In Business Ethics: An Examination And Critique, Kristen Bell Detienne, Carol Frogley Ellertson, Marc-Charles Ingerson, William R. Dudley

Faculty Publications

The field of behavioral ethics has seen considerable growth over the last few decades. One of the most significant concerns facing this interdisciplinary field of research is the moral judgment-action gap. The moral judgment-action gap is the inconsistency people display when they know what is right but do what they know is wrong. Much of the research in the field of behavioral ethics is based on (or in response to) early work in moral psychology and American psychologist Lawrence Kohlberg’s foundational cognitive model of moral development. However, Kohlberg’s model of moral development lacks a compelling explanation for the judgment-action gap. …
